Chemical composition % of the ladle analysis of grade ASTM A529 Grade 42 and Standards
ASTM A529 Grade 42 3/16 to 1/2 in. thick, as-rolled steel plate
Categories: Metal; Ferrous Metal; ASTM Steel; Carbon Steel; Low Carbon steel
Material Notes: A low cost grade limited to 1/2 inch thickness, used occasionally for non-demanding applications.
The following are suggested consumables for arc welding processes for 0.476 - 1.27 cm (3/16 - 1/2 in.) thicknesses. For Manual Shielded Metal-Arc (AWS A5.5) use Low Hydrogen Electrodes E60xx, and E70xx. For Submerged Arc (AWS A5.23) use F6x-Exxx, and F7x-Exxx. For Gas Metal-Arc (AWS A5.28) use ER70S-x. For Flux Cored-Arc (AWS A5.29) use E6xT-x, and E7xT-x except -2, -3, -10, or -GS.

Principal Design Features
One of the most widely used precipitation hardening grades in the business. While soft and ductile in the solution annealed condition, it is capable of high properties with a single precipitation or aging treatment. Characterized by good corrosion resistance, high harness, toughness and strength.
Machinability
Long, gummy chips characterize this alloys machinability. It can be machined in the annealed condition, however condition H1150M will yield best results. Post machining solution treatment of parts will be required prior to final hardening if machining in this condition.
Heat Treatment
CONDITION A--Soak at 1900 F (1038 C) for 30 minutes and cool below 60 F (16 C) for complete martensite transformation. CONDITION H 950- Treat Condition A material at 900 F(482 C) for 1 hour, air cool.. CONDITION H925, H1025, H1075, H1100, H1150- Soak solution treated material for 4 hours at specified temperature, air cool, CONDITION H1150M- Soak solution treated material at 1400 F (760 C) for 2 hours, air cool, then re-heat to 1150 F (620 C) for 4 hours and air cool.
Welding
Successfully welded by common fusion and resistance methods, this alloy should not be joined by oxyacetylene welding. AWS E/ER630 filler metal is recommended if required.
Forging
Soak for 1 hour at 2150 F (1177 C) prior to forging. Do not work below 1850 F (1010 C). Post-work solution treatment is required prior to final hardening.
